2. Greenhouses Also called Glasshouses
They are buildings where plants are grown. They vary in sizes from small sheds to very large buildings
Miniature greenhouses are known as Cold Frames

3. The process of the Greenhouse
Heats up! (glass is transparent)
Warm up the house in cold days!

4. USES OF THE GREENHOUSE! protect crops from too much heat or cold
shield plants from dust storms and blizzards
help to keep out pests

5. The greenhouse Effect! :D
A process by which thermal radiation from a planetary surface is absorbed by atmospheric greenhouse gases, and is re-radiated in all directions

6. Greenhouse Gases!
Gases in the atmosphere that absorb and emit radiations within the thermal infrared range.

7. The most important greenhouse gases in Earth’s atmosphere are:

14. The atmosphere as a greenhouse!
Warm up the earth on cold days!

15. Greenhouse Gases have a great affect on the temperature of the Earth; without them, Earth's surface would be on average about 34 °C (59 °F) colder

16. CFC

Northern regions are expected to be particularly hard hit. The Canadian Arctic is already experiencing warmer weather, shorter winters, melting permafrost, wildlife impacts and disruptions of traditional Inuit lifestyles.
